Specification of Letters Patent.

Patented Aug. 1?, 1915.

To (:15 whom it may concern Be it known that we, CARL Gr. SWEBILIUS and Haxs T. B. HAxiTz, a citizen of the United States and a subject of the Emperor of Germany, respectively, residing at New Haven, Xew I-laven county, State of Connecticut. have invented certain new and useful Improvements in Gun-Sights, of whlch the following is a full,-clear, and exact dev scription.

Our invention relates .to an improved gun sight; the object being to provide simple and effective means for shifting sight both vertically and laterally to effect the necessary adjustment for elevation and windage.

In the accompr "lying drawings: Flgure 1 is a. plan view of our sight as it would appear on a rifle barrel and relatively enlarged. Fig. 2 is across-section on, the line 2 Fig. 3 is a section on the line 33. Fig. 4 is a perspective view of the sight frame. Fig. 5 is a perspective view-of the sight proper detached. Figs. 6 and 7 are conventional views of details. I

1 represents part of a rifle barrel upo which the sight is mounted in any suitable manner. In this particular instance, thetop of the barrel is provided with an undercut groove to receive the dove-tailed base 2 of the sight frame. The sight proper comprises the part 3 over which the sight is taken. In this instance the sight is taken through a groove 4 in the upper flat surface of the part 3. At one end of the part 3 is a hub upon which is mounted an operating member (5, The member 6 is so mounted on the hub 5 that the latter may slide in, but not rotate independently of the operating member 6. At-the other end of the part 3 is a threaded hub 7'upon which is mounted an operating device '8, the latter being threaded on the part 7.- At each end of the.

base 2 of the sight frame are suitable brack ets, in this instance in the form of rings 9--9-10--l0, which aiford bearings for the hub ends 5-4 respectively, the rings 9-9 being spaced properly to afford room for the operating member 6. the rings 1010 being properly spaced to afford room for the operating member 8.

Suitable means are employed to prevent the operating members 6-8 from accidentally turning out of their ad usted positions. In the preferred form of such means shown the forward end of the barrel.

in the drawings, we employ a double-ended spring seated in a suitable groove in the bottom of the base 2, said groove intersecting the space between the rings 99' and 1010, so that the spring ends will frictionally engage the edges of the operating mem bers 6S, forexample, the end 11 of the spring engages the operating member 6, while the end 12 engages theoperating menu ber S. The operating members G 8 preferably have t eir outer edges toothed to be more readily ngaged and held by the spring ends 11 12. The part 3 of the sight is preferably triangular in cross-section (see dotted lines, Fig. 3); and the sharp edge is preferably slightly notched as at t in line of the barrel or line of sight, the sight is adj usted for the highest elevation of the gun, assuming the sight shown to be located at T0 lower the elevation of the gun the sight is gradually turned by the member 6, thus rela tively raising the edge having the sighting notch 4. until the desired elevation has beer secured. This may be increased at will until the lowest elevation is obtained, which occurs when the grooved surface of the sight body 3 stands vertically, that is to say, in a plane at right angles to the axis of the barrel, instead of a plane parallel to the axis of the barrel as shown in the drawings. adjust the sight for windage, that is to say, to shift the sight laterally so as to make due allowance for a side wind. the operator turns the operating members in'the proper direc tion to shift the sight groove 4: and notch 4"" laterally to the necessary degree. If (1;- sired, the notches between the teeth at the edge of each operating member 6S may be utilized as gage marks. the operating device (5 has been turned the distance of one tooth. it may indicate a. certain arbitrary degree of change in the elevaoperating member 8 the distance of one F or example. when w tooth, may indicate a, certain arbitrary degree of lateral displacement of the effective part of the sight. V I Such a sight may be used on" any kind of a gun and may be employed either as a rear sight or a front sight, although usually sucht sights are employed near the rear of the bar-- rel. The bottom of the notch P, which is of course, co-incident with the bottom ofthe longitudinal groove 4 when the latter is provided, constitutes the sighting point, and as that point is eccentric to the axis of the v sight body and hubs 5-47, it is clear that this degree between device.

sighting point may beraised, lowered, shifted to the right or left at will to any desired the extreme limits of the What we claim is:

1. A gun sight comprising a. main body arranged-to rotate'onan axis transverse to the barrel ofa gun on which it.is to be transversely relatively to said gun barrel, said-"body having a sighting point located mounted, and also arranged to bemoved relatively to the ax'isof rotation of the sight body so that the rotation\of said b'ody will relatively elevate and depress said sighting 1 point,' w,ith means for'rotating saidfsight 'body and for shifting the same tran versely to the agis of the barrel;

2. A gun sight comprising a frame, a

l main sight body rotatably mounted in said frame transversely to the line of sight, said body,.-being provided with a sighting point,

means for rotating said main body. to elevate and to depress said sighting point.

main sight body rotatably mounted in said frame transversely to the line of sight, said body being provided with a sighting point,

means for rotating said main body to eletransversely to the line of sight, said body being provided with a sighting point, means for rotating. saidmain body to elevate and tofdepress said sighting point, and to shift said sighting point laterally relatively to the line of sight, said means comprising two independently movable parts, one of said parts being mounted at one end of said sight body, the other part'bein mounted at the otherend ofsaid sight bo y. I 6 [A frame, a main sight body rotatably mounte at its ends in said frame, the intermediate portion of said body havinga notch,-the bottom of which forms a sighting point, said sighting point being eccentric to the axis of rotation of the body, with means to rotate said body to elevate'a-nd depress said sight-v ing point-and with other means to shift said sighting point laterally to the line of sight, without disturbing the elevation of the sighting point. 1

7. In a sight, a frame including two sets of spaced; annular supports at -each end, a main. sight body having hubs' atv each end mounted for rotation in said annular supports, an operating device slidably mounted on one hub with means for vholding said operating device and hub from independent rotation, said operating device being arranged between the annular supports comprising one set, another operating device mounted to rotate on theother hub and ineluding a threaded connection between said 1 .parts, said last mentioned operating device being arranged between the two annular" supports constituting the otherset, and said body having a sighting point located upon an intermediate part thereof and eccentric to its axis of rotation.'
